From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
From the Linux sungem driver, we know that the multicast filter CRC is
implemented using ether_crc_le() which isn't the same as calling zlib's
crc32() function (the zlib implementation requires a complemented initial value
and also returns the complemented result).
Fix the multicast filter by simply using the new net_crc32_le() function.
